SIHOO Doro C300
$200 under the $500 cap
The only sub-$300 pick that is genuinely full mesh — mesh seat and back — where seven of nine rivals here hide foam under the mesh. 12 sources.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
A tensioned mesh seat pan can dig in. Over 6+ hour sessions it presses at the front edge of your thighs — the single most common complaint about full-mesh budget chairs. SIHOO also publishes no seat-height range at all, and third-party measurement puts the travel at only about 2 inches, which is narrow.
Dealbreaker? Duramont ($198.99) puts foam under a mesh back for $101 less ↓

Traps — this verdict avoids
Why the SIHOO Doro C300 is right for you
It avoids every trap below — and for anyone, under $500, it is the pick because it delivers:
"Mesh" means three different things
Only 2 of the 9 chairs here have a mesh SEAT as well as a mesh back. The other seven are a mesh back over a foam or fabric pad — cooler than all-foam, but your thighs still sit on foam. And no chair under $500 uses true elastomeric suspension mesh, the Aeron-style load-bearing membrane people picture when they type "mesh chair".
Capacity is the wrong-buy
Rated user weight spans 275 to 440 lb across these nine picks and marketing never leads with it. Both Branch chairs are rated 275 lb — the lowest here, on the two most expensive chairs — while the $146.99 SIHOO M18 is rated 330 lb. Ratings are static-load figures; real use reduces effective capacity.
Sag ends the chair
Low-cost tensioned mesh commonly slackens within 12–24 months, and none of these chairs has user-replaceable mesh — once it goes, the chair is done. Steelcase and HON sell replacement cylinders, casters and arm pads through their service channels; the budget brands generally do not.
